SPEGIFIGATION forming part of Letters Patent No. 23l,7'72,'dated August 31, 1880.

' Application filed April 22, 1880. (No model.)

To all whom it may concern:

Be it known that I, DAVID G. DAVISON, of Paris, in the county of Edgar and State of Illinois, have invented certain new and useful Improvements in Saw-Sets; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

The nature of my invention consists in the construction and arrangement of a saw-set, as will be hereinafter morefully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will 110w proceed to de scribe its construction and operation.

Figure 1 is a perspective view of my sawset. Fig. 2 is a longitudinal section of the same.

A represents a straight metal bar of any suitable dimension, formed near one end with a step or projection, B, as shown, extending 011 one side at right angles to the bar. On the opposite side the bar is formed with a deep longitudinal groove, a, extending the entire length of the bar, and the end of the bar beyond the step B is cut entirely through, making this end forked. In this forked end of the bar is, by means of a pin, b, pivoted a plate or set, C. The pivot-pin 1) passes through the set at the back near the outer end, and the front of the set near the inner end forms, a bevel, d, and below the same is inserted a dovetailed copper plate or die, z'. In the step B, directly in front of the copper plate 43, is inserted a dovetailed steel die, h.

The inner end of the set 0 forms a rounded projection, m, which enters a corresponding recess in the end of a lever, D, pivoted in the grooved barA, and having its lower end thrown outward by a spring, F.

This saw-set is operated as follows: It is held in the hand and the step or projection B placed against the side of the saw-tooth, the point of the tooth coming against the copper plate 1'. By now closing the hand, so that the lever D will be forced into the bar A, the set C is turned so that its bevel d, in connection with the beveled edge of the die It, will set the tooth.

n is an adjustable stop in the bar A, against which the lever D closes for regulating the amount of the set.

I am aware that saw-sets have been constructed with a stationary bed-plate, removable die, soft-metal abutment-plate, and beveled set, and hence do not claim such, broadly, as my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isv The within-described saw-set, consisting of the grooved and forked bar A, step B, with die h, pivoted set C, with bevel d, plate 1 and tooth m, thelever D, spring F, and stop a, all.

constructed substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
